    Problem Summary Our system will not allow a process to have an RLIMIT_STACK limit
    (either current or max) set to
    RLIM_INFINITY.
    Problem Text In VSU tset/CAPI.os/procenv/setrlimit/, the test for Assertion 5
    attempts to use setrlimit() to change
    the rlim_cur and rlim_max limits to RLIM_INFINITY for the following
    system resources:
    RLIMIT_CORE
    RLIMIT_CPU
    RLIMIT_DATA
    RLIMIT_FSIZE
    RLIMIT_NOFILE
    RLIMIT_STACK
    RLIMIT_AS
    On our implementation this test fails for RLIMIT_STACK, as we do not
    support extending the stack
    segment without limit. Making stack size unlimited has potential
    security concerns related to buffer
    overflows and we will need more time to investigate the impact.
